There are several sites with instant quotes that are cheaper than Shapeways.
PCBWay and JLCPCB both offer similarly-priced very cheap 3d printing and CNC services out of China. Weerg in Italy also offers 3d printing and CNC services and I'm probably going to try them out for the next thing I need printed. The only non-marketplace service I've seen in the US that offers instant quotes is i-solids in Texas, but they have quite high startup costs and seem to be more geared towards small-medium production runs.
